Abstract
This article presents a successful endeavour towards destabilization of an aqueous suspension of carbon nanoparticles via synthesized hydrolyzed graft copolymer (Hyd. GGI-g-PAM) of gum ghatti. Flocculation proficiency of the preformed graft copolymer of gum ghatti (GGI-g-PAM) has been amplified via partial alkaline hydrolysis that helps in straightening and uncoiling of the grafted monomer chains consequently increasing radius of gyration and hence the hydrodynamic volume of the molecule. Standard jar test procedure has been followed to analyze and compare the flocculation proficiency of the novel product with that of both the gum ghatti and GGI-g-PAM in coal-fine suspension as well as in aqueous suspensions of MWCNTs.
